2000101;Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb 2 S 3), the
Various methods such as gravity concentration, flotation, panning,
In the recovery process, such low purity metals are converted into crude precious metals by repeated dissolution, filtration, concentration and reduction. Crude
In this work, two hydrometallurgical processes for gold recovery are explored for a small-scale gold mining case study located at Ponce Enriquez, Azuay, Ecuador.
